Chapter 448 There was a sudden knock on the door

At this time, the white-haired old man suddenly remembered something and asked:

"Don't implement this plan immediately. Since Xu You can still communicate with Mr. SPY about technical issues today, it proves that his brain is not seriously damaged yet. Wait for a while and there is definite news before implementing it.

It’s not too late to plan.”

"Okay, sir. According to the results of our previous experiments, such lesions are irreversible and will continue to worsen. Mr. SPY will continue to provide us with information in the future. If Xu You can't even see Mr. SPY,

That really means that he no longer has the ability to think."

"Well, it's best to be fully prepared. In addition to Xu You, we also need to observe the behavior of the people around him, especially his girlfriend."

"Understood, we will continue to pay attention."

…

Arithmetic Quantum Laboratory.

Xu Youzheng is using the function of the wireless brain computer to form a connection channel with the quantum computer.

Since Huang Sibai returned to China and joined Fulong Technology, he has contributed more than ten technologies related to EUV lithography machines to the company.

Each of these technologies, including the laser light source, workbench, lens, etc. of EUV lithography machines, is a real key technology. It is a very significant progress for domestic EUV lithography machines.

However, because a photolithography machine involves too many components, and it requires the cooperation of many companies in the industry chain to achieve mass production.

In a short period of time, it is not possible to build a real EUV lithography machine immediately.

As a scientific research expert in many fields, Xu You naturally understands this truth.

But if we can let computational artificial intelligence master this knowledge, the situation will be completely different.

Through the function of the wireless brain computer, Xu You transferred all his knowledge to Suan Jing, and allowed Suan Jing to understand the meaning of the lithography machine.

Under such circumstances, Xu You continued to activate the skills of brain simulation, using the powerful computing power of calculations to continuously simulate the operation process of the lithography machine in his mind, optimizing the details of each component.

At this time, tens of thousands of components of a photolithography machine were clearly visible in Xu You's brain.

"There is indeed no problem with the technologies Huang Sibai told me."

Through rigorous simulations, Xu You confirmed the authenticity of Huang Sibai's technologies.

In order to gain Xu You's trust, Huang Sibai did not hide anything from Xu You and told Xu You everything he learned.

From Huang Sibai's narration, Xu You could tell that these technologies were not really developed by Huang Sibai himself, but more likely that Huang Sibai obtained them from certain channels.

But for Xu You, this information is enough.

In deep thinking, Xu You can derive more useful information based on the information provided by Huang Sibai.

After constant simulation, calculation, and deduction, Xu You is getting closer and closer to a complete set of EUV lithography machine technology.

Multiple processes including surface cleaning and drying of silicon wafers, priming, rotating photoresist, soft baking, alignment exposure, post-baking, development, hard baking, etching, detection, etc. were constantly repeated in Xu You's mind.

With.

After countless deductions, Xu You still failed to successfully produce a qualified high-precision chip based on the EUV lithography machine simulated in his brain.

"No...the technology of EUV light source has not been solved well yet."

In EUV lithography machines, EUV light source is undoubtedly the core equipment.

In order for the lithography machine to work efficiently, it needs a bright enough EUV light source.

In terms of EUV light sources, Huang Sibai provided some technologies, but they did not completely solve the problem.

"Wait a minute... the spectrum of extreme ultraviolet radiation seems to have room for further optimization!"

At this time, Xu You suddenly noticed.

Under the normal laser optimal focus position, there is a lack of effective coupling between the incident laser energy and the plasma.

The reason is that at the optimal focusing position, the focused spot size is small and the laser focusing cone angle is also small. The energy absorbed by the plasma will be localized near the central axis, affecting the absorption of laser energy by the plasma.

In other words, the so-called "best focus position of the laser" is probably not the position with the strongest EUV spectrum intensity.

"If you adjust the size of the focused spot... the situation will be different."

According to Xu You's theory, when the focused spot size increases slightly, the laser focusing cone angle will also increase.

In this way, the laser energy will be effectively distributed at the front edge of the entire plasma, and the plasma can effectively absorb the laser energy and reduce energy loss.

Of course, the focusing spot size cannot be increased too much, otherwise, it will have the opposite effect.

However, even though Xu You had these inferences, it was difficult to find the optimal focused spot size within a limited time just relying on his own computing power.

Fortunately, Xu You can rely on the powerful computing power of the calculation to greatly improve his calculation speed.

After many calculations, Xu You finally found the position with the strongest EUV spectrum intensity.

After replacing the new EUV light source device, Xu You re-deduced the workflow of the lithography machine.

Just as Xu You expected, when the brightness of the light source increased greatly, the working efficiency of the lithography machine also improved a lot.

"If it can work with such efficiency, then this EUV lithography machine may really be put into use!"

After determining the design plan of the photolithography machine, Xu You still needs to summarize the specific processes of each component.

Because, I want to create such a precise instrument like a photolithography machine.

Simply relying on design drawings is not enough.

If there is no specific process, even if you get the design drawing, it does not mean that you can manufacture the entire photolithography machine.

Xu You didn't bother to take a rest and continued to work on the next work with Suan Jing.

…

In Xu You's laboratory, Lin Shi was anxiously asking Cui Ying something.

"Mr. Cui, why didn't Mr. Xu come to the laboratory today? Do we need to go take a look at him?"

"No, Teacher Xu may be a little tired recently and needs to rest for a while. I won't show up in the laboratory for the time being. Lin Shi, even if Teacher Xu is not here, you must take the lead and continue the research work on several projects.

."

"Okay, Teacher Cui, I understand."

Lin Shi was still vaguely worried about Xu You, but since Cui Ying said so, Lin Shi couldn't ask any more questions.

When Xu You is away, Lin Shi should take the lead and continue Xu You's unfinished scientific research projects.

At this moment, there was a sudden knock on the laboratory door.
